I spend an unhealthy amount of time thinking about CDNs. Wrote up a blog post for people starting on the journey. jeet.world/practical-cdn-cac…

And that beings an end to the 4th IPL I have been a part of streaming… (via JioCinema and now) @JioHotstar! ✨🙂

Add OpenAI/Anthropic tokens/credits to this?

The biggest RL Hackathon in the world is happening next weekend in the campus of @Scaler_SST next weekend. 1500 finalists from 75000 participants will be building RL environments. Looking for mentors to guide people, and take sessions. You must have prior experience with RL. Best place to meet solid young talent in the AI space, along with @AIatMeta and @huggingface tech mentors. My DMs are open, ping if you've worked on RL and can join as mentor.

Looking for enterprise codebases in languages that are relatively rare in the Open Source World, primarily: C#, Scala, COBOL, Sysverilog/Verilog, PHP, Kotlin, CUDA, Fortran, ABAP, OCaml, Slang. The purpose is to teach next generation of machines and humans. Cost not a constraint for a rich repo! X, do the magic!

Last night I got to sit in on @lossfunk's invite‑only meet, and my brain is still buzzing. Talent density was off the charts... @paraschopra in the room, folks like @jiten, @asxna, @_anshuman26, and a fantastic deep‑dive by @Naman_Bhalla on RL environments and reward hacking.

Looking to connect with folks who actively work in 'legacy-ish' / niche stacks like COBOL, modern Fortran, Ada, Verilog, Erlang/Elixir, Perl. If you’ve shipped real systems in any of these (or know someone who has), my DMs are open – want to route you to some interesting opportunities. If you haven't, please 🔁 for good karma.

🚨 JioHotstar Design is Hiring! We’re designing what the world streams next — and looking for talented folks to join us at our Bangalore HQ.

Let that sink in... a platform built from the ground up just streamed over 72.5MN fans at the same time. With personalized ads, real‑time commentary, rich match analytics and a tidal wave of emotions all holding steady. A double win for the @JioHotstar engineering and product teams... we broke global streaming records and then stayed on to celebrate India lifting the T20 World Cup trophy together.

If you folks ever wonder how live streaming works and what goes on behind the scenes, this is what you should watch: my conversation with Prachi - the absolute best person to talk about live streaming. Her career is all-things-live-streaming. Here's the pod - youtube.com/watch?v=36N1Bz7q…

History, streamed. JioHotstar has set a new global benchmark in live streaming, recording 65.2 million peak concurrent viewers and 619 million views during the India vs England semi-final of the ICC Men’s T20 World Cup 2026—making it the most streamed live event in the world.

I am hiring senior engineers for my Live Streaming team. Please apply directly and retweet so that good candidates can discover this opportunity. jobs.lever.co/jiostar/f482a7…

an ai for an ai makes the whole world agentic - Lol :)

Looking forward to this new meetup by our team.

Enrollments are now open for the System Design Feb Cohort. I have changed and, more importantly, added so many things in my cohort in the last 6 months that it is now deeper, crisper, and more fun than ever :) The course is not theoretical junk, but it is highly practical and filled with discussions, brainstorming, and questions. The sessions do not end until every single question is answered. Here are some key aspects of the course - Build 25 systems in 8 weeks - 45 hours of Live Classes on Weekends - Lifetime access to the recordings - Open forums where you discuss anything literally - A ton of brainstorming to make sure you build the intuition Given that we have a lot of experienced people (leads, staff, and even principal engineers) who join the course, they share stories and nuances about similar systems they worked on at their workplaces, and that's priceless :) We discuss all possible trade-offs and understand the right reasoning behind opting for a particular approach. We naturally evolve our solution and do not go straight from question to answer. Because there is no one way to design a system. So, if you are an SDE-2, SDE-3, staff, or even a principal engineer, and looking to build a rock-solid intuition to design any and every system, or just want to have some good technical discussions over the weekends, join the cohort. Go through other testimonials on the course page to understand what people feel about the course. The most common thing I get is how I sparked their engineering curiosity and helped them become better engineer :) Feb cohort starts Jan 31st :) And about ~64 seats are left.

Had to rub my eyes a bit after seeing this. I went and checked all the other usual suspects (Phonepe, Paytm, Meesho, Flipkart) to be sure, and yes it does seem like @JioHotstar is the first Indian app to cross 1B downloads on Play Store! Congratulations @akisaxena @jiten!
